摘要
针对传统金相复型技术中AC纸与检测面贴合不紧密、复型后卷曲以及丙酮溶剂干扰等长期存在的技术瓶颈,提出一种纳米隔离层的背胶复合AC纸复型技术。通过跨尺度结构设计,构建AC纸-碳/铂纳米层-粘胶层-贴纸层四维复合结构。在AC纸表面喷涂10~30 nm的碳或铂纳米颗粒,以此构建高性能隔离层,进而实现双面胶层界面调控。SEM与润湿角测试表明,纳米颗粒喷涂后形成致密疏水屏障,能有效抑制溶剂渗透,使丙酮溶剂渗透率降低87%以上。纳米压痕测试证实,喷涂形成的25 nm厚非晶碳/铂膜使膜材刚度提升了47.12%,有效避免了复型过程中气泡与褶皱的产生。
Aiming to address the long-standing technical bottlenecks in traditional metallographic replica techniques,such as the weak adhesion between AC paper and the detection surface,curling after replication,and interference from acetone solvent.A back-glued composite AC paper replication technology with a nano-isolation layer was proposed.Through a cross-scale structural design,a four-dimensional composite structure comprising AC paper,a carbon/platinum nanolayer,an adhesive layer,and a sticker layer was constructed.Carbon or platinum nanoparticles,ranging from 10 to 30 nm in size,are applied to the surface of AC paper to create a high-performance isolation layer.This process facilitates the regulation of the interface within the double-sided adhesive layer.The results of SEM and wetting angle tests indicate that the application of nanoparticles leads to the formation of a dense hydrophobic barrier.This barrier effectively inhibits solvent penetration,resulting in a reduction of acetone solvent permeability by over 87%.Furthermore,nanoindentation tests have confirmed that the amorphous carbon/platinum film,with a thickness of 25 nm formed through spraying,enhances the rigidity of the film material by 47.12%.This improvement significantly mitigates the occurrence of bubbles and wrinkles during the replication process.
